Abstract:
The present investigation was carried at Sam Higginbottom University of Agriculture Technology and Sciences to assess the Physicochemical properties of black cotton soils from different blocks of Guntur district, Andhra Pradesh, India. A total of twenty-seven soil samples were collected randomly from different depths, i.e., 0-15cm,15-30 cm, and 30-45cm. The study area consists of mostly black cotton soil. These soils were moderate to strongly alkaline in reaction and non-saline. On the soil complex, the dominant cation is calcium. The overall fertility status of the soils was low, medium, and high in nitrogen, phosphorus, and potassium respectively. The calcium and magnesium ranges are high in these clay soils. The sulfur is sufficient in these clay soils. As the soils were calcareous and strongly alkaline, there is a need for the application of any acid-forming amendment (S containing amendments) and organic materials to alleviate the nutrient deficiency and improve productivity.
